To all whom it may concern;

Be it known that 1, Jon Huss .it, a citizen of the United States of America, residing at Cleveland, in the county of Cuyahoga andState of Ohio, have invented certain new and useful Improvements in Spark Ar- This invention relates to new and useful in'iprovements in spark arresters.

T he primary object of the invention is to provide a device which may be detachably secured to a stack for arresting the sparks discharged therefrom with smoke or other gases.

A further object of the invention is to provide a novel form of mounting for a spark arr-ester by means of which the latter may be adjustably secured to a stack.

A still further object of the invention is to provide a spark arr-ester of the above mentioned type which is of exceedingly simple construction and one that may be easily and quickly mounted in place.

Other objects and advantages of the invention will be apparent during the course of the following description.

in the accompanying drawing forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

Figure 1 is a side elevational view of the spark arrester shown mounted upon a smoke stack, shown in dotted lines,

Figure 2 is a top plan view of the spark arrester shown in Fig. 1,

Figure 3 is a central vertical sectional view of the spark arrester shown in Figs. 1 and 2, and

Figure 4 illustrates a modified form of mounting for the arrester.

in the drawing, wherein for the purpose of illustration is shown a preferred embodiment of this invention, the numeral 5 designates the upper or discharge end of a stack.

in Figs. 1 to 3 inclusive, a two-part collar 6 is illustrated as consisting of the parts a and -b which are of substantially semicircular form and have their opposite ends bent laterally to form the lugs 7 which are apertured for receiving the clamping bolts 8 by means of which the collar may be adjustably secured to the stack 5. Suitably secured to the intermediate portion of each collar part is the foot portion 9 of a substantially U-shaped bracket 10 which the following is a specihas its'upper end bent inwardly to form a supporting lug 11. Clamped" between the laterally proyecting ends of the collar parts are the foot portions 12 of the arcuate brackets 13 which have their upper ends bent laterally to form the supporting lugs 14.

The spark arrester screen 15 is of disk formation and has its peripheral edge clamped between the superimposed two part clamping rings 16 and 17 which are formed of the semi-circular part e and -z Z-- respectively. it will be noticed that the mating ends of the parts 6' of the ring 16 are arranged at right angles to the mating ends of the parts ri of the ring 1?. The overlapping .of these ring parts will materially strengthen the structure 111st described. These ring parts are bolted together by the fastening means 18 which have the nut locking wires 19 threaded thru suitable openings formed in the bolt portions of the fastenlng means. These fastening means 18 are also employed for mounting the screen 15 and rings 16 and 17 upon the supporting lugs 11 and 14 of the brackets 10 and 13.

It will beseen that by loosening the clamping bolts 8, the collar 6 may be adjusted longitudinally of the stack 5 for varying the distance between the discharge orifice of the said stack and the screen 15.

In Fig. 4 there is shown a modified form of mounting for the arresting screen 15 which will permit the ready adjustment of the latter to vary its distance from the discharge orifice of the stack 5. In this figure the numeral 5 designates the stack which has'permanently secured thereto the angle brackets 20 having internally threaded enlargements 21 formed on the outer ends thereof. While only one bracket is shown in this figure, it is to be understood that a suitable number of the same are to be provided and mounted upon the stack 5 in the manner illustrated. Encircling this stack 5 is a collar 6 which is intended to be formed of two parts in the same manner as the collar 6, shown in Figs. 1 to 3 inclusive, but the collar 6 is to be formed with a diameter greater than the external diameter of the stack 5. The collar 6 is formed of this diameter to permit the same to slide freely upon the stack. The collar 6 is provided with the same kind of brackets as those designated by the numerals 10 and 13 in Figs. 1 to 8 inclusive. Each r of these brackets of a similar construction rotatably receives the upper end '23 of the 7 threaded rod 24. This threaded rod is connected to the bracket 10 by therings'24" to prevent the rod from separating from the said bracket. The'thr'e'aded portion of thisrod is mounted within the bore of the enlargedz-p0rtion21of the bracket "20 and engages the threads formed in the samefor caasin-g lm gitiidinal movement of the collar 6 in respect to the stack z) when -th'e 'ro'd is rotated. The lower end of this rod is provided with a winged head '24 bymeans of which the said rod may be rotated inanually;

It is tobe understood that the forins: of this invention herewith shoWnan'd described are to be taken'as preferred examples of the same, and that various changes in the shape size, and arrangement of parts may be resorted to vvithont' departing from the spirit of the invention or the scope of the subjoined claim;

Having thus described the invention, I clai mzf I I V In a' spark arr-ester, a mounting collar formed of two parts With the parts having mating-apertured ears for receiving connecting b0l ts,-a U-shaped bracket fastened to each' collar'part with one side arranged in parallelism with the plane of the collar, an

arc'uate bracket clamped at its lower end clnding a disk-shaped screen, and two p'art clamping, rings overlying and underlying said screen and bolted thereto and to the said brackets, the parts of said rings being 'of semi-circularshape and arranged in respectto eachother \vith'theinating ends of one ring arranged atright angles to the mating ends of the other ring.

In testimony whereof I affix my signature.
